A series of novel (E)-4-oxo-2-crotonamide derivatives were designed and synthesized to find potent antituberculosis agents. All the target compounds were evaluated for their in vitro activity against Mycobacterium tuberculosis H37Rv(MTB). Results reveal that 4-phenyl moiety at part A and short methyl group at part C were found to be favorable. Most of the derivatives displayed promising activity against MTB with MIC ranging from 0.125 to 4 μg/mL. Especially, compound IIIa16 was found to have the best activity with MIC of 0.125 μg/mL against MTB and with MIC in the range of 0.05–0.48 μg/mL against drug-resistant clinical MTB isolates.

Protein kinase B (PknB) is an essential serine/threonine protein kinase required for Mycobacterium tuberculosis (M. tb) cell division and cell-wall biosynthesis. A high throughput screen using PknB identified a (E)-4-oxo-crotonic acid inhibitor, named YH-8, which was used as a scaffold for SAR investigations. A significant improvement in enzyme affinity was achieved. The results indicated that the α,β-unsaturated ketone scaffold and “trans-” configuration are essential for the activity against PknB. And compounds with an aryl group, especially with electron-withdrawing substituents on benzene ring, exhibited four fold potency than that of YH-8.

3-(4-Phenoxybenzoyl)propionic acids were prepared and tested for hypolipidemic activity in normal rats. A structure-activity relationship study showed that the 2-acetylthio derivative had hypolipidemic activity. Among these compounds, 2-acetylthio-[3-(4-c
